To all 'whom 'it may concern:

Be it known that we, THOMAS S. HUDSON and ANTHONY HARDY, of EastCambridge, in the county of Middlesexand Stateot' Massachusetts, haveinvented anew and useful Improved Machine for Canceling Revenue-Stamps;and we do hereby declare the same to be fully described in the followingspecification and represented in the accompanyingdrawings, of whichiFigure l is a side elevation. Fig. 2 a central and'longitudinal section,and Fig. 3 a.

transverse section, of it.

The natureof the main part of our invention consists in combining withdevices used for printing the month and year, or the name or names ot'one or more persons, plaees,orthings, a changeable mechanism or seriesof types by which the day ofthe month, whatever such may be, may also beprinted at the same time with the other imprints made by the devices-above mentioned; and our invention further consists in combining withthe aforesaid canceling or printing devices a chamber or receiver forholding the types indicative of the months, or the years and months; andour invention further consists in the combination of a chase or separatetype carrier or holder with the plunger, and the series of changeabletypes,

' to be hereinafterdescribed.

In the drawings, A denotes the frame of the machine, it .beingconstructed of the form represented, or in any other suitable for thepurpose.- lt has a bed, a, on which the papercarrying the stamp to becanceled is to rest while bein gimprinted by the machine. The said framesupports-a tubular plunger, B, which isprovided with aspring, b, for'elevating it; anditalso has a head, c, on its top, such head being toreceive the blow of a persons hand when applied to the plunger for thepurpose ot' depressing it toward the bed. There is a rectangular cavity,d, formed in the neck e of the frame, and provided with a cover, f, suchcavitybeing to contain the types for printing the names of the varionsmonths and'years. i

At the lower part of the plunger there are sockets g g, for thereception of projections It h from the chase h', which is held to theplunger vby one or more clamp-screws, t'. This chase, formed in underside view as shown in Fig. 4', and in side view in Fig. 5, is a typesomade as to be jcapflble ot' printing the name or words that do notrequire to be changed-as, for instance, the name ot' a person orplace-and it` contains tapering recesses or chambers k k for holdingother types for printing the name of a within the plunger inzmannerasshown inV the drawings. The said endless chain m is to Containthirty-one links, which are to have pro-- -jecting from them gures forprinting the various numbers, from one to thirty-one, indicative ofthedays ot' a month. On the shaft n i.

of the upper sprocket-wheel isa catch-Wheel, o, provided with aspring-catch, p, projecting from the'head c, the same serving to fix thechain in position when any one'of its links may be brought into itsplace for printing..

A printing-ribbon, D, applied to wind on two axles, q r, arranged inmanner :1s-shown in the drawings, extends underneath and against the prin tin g-surface ofthechase, such printingribbon being covered with apigment or com position'which will offset when pressed on paper by thechase and its type.

To the bottomotl the frame A we apply one or more elastic cushions ormasses, s s, of vulcanized india-rubber, the same bei-ng not only toprevent noise, but to relieve 'the hand from the effects ot' the blow ontlie ,head of the pun ger durn g the act of driving'the plungerdownward. They also serve tob protect the types from the effect ot'concussion.

The mode of operating our invention is to place the paper having therevenue-stamp on it on the bed, and by a blow of the hand on the head otthe plunger force the plunger and the printing-ribbon down upon thestamp, so as to cause an imprint to take place on the stamp.

I Our invention also is applicable to poststamping letters, as Well asvarious other uses.

What we claim as our invention is- 1. The combination of the endlesschain of types and its carrying mechanism with the plunger. y

2. The combination of' the endless chain of types and its carryingmechanism with the plunger and the chase, the 'Whole being :Lrrangedtogether as specified.

The combination ot' the endless chain of types and its carryingmechanism with the chase, the plunger, and printing-ribbon, arranged asspecified. y

4. The combination of the type-chamber d in the neck c of the frame withthe endless chain of type, its carrying mechanism7l the chase, andthe'plunger, arranged to operate as described.
